, DEVICE FOR RAISING OR LOWERING PIPE.

EPECIFICATION forming part of Letters PatentNo. 375.985. dated January 3, 1888.

l a Application filed July 7, 1887. Serial No. 243,633. (No model.)

To all whom it may concern:

Be it known that I, LEWIs BooEE, a citizen of the UnitedStates, residingat Buffalo, in the county of Erie and State of New York, have invented certain new and useful Improvements in Devices for Raising or Lowering Pipes; and Ido hereby declare the'following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same,

reference being bad to the accompanying drawings, and to letters or figures of reference marked thereon, which form a part of this specification.

My invention consists of a device of simple but effective construction by means of which the danger now attendant upon raising and lowering heavy pipes in trenches is entirely avoided and a saving in time and labor is effected. a

, I will now proceed to describe the manner in which my invention is to be carried into effect.

y In the drawings, Figure 1 is a top plan view, 2 5 and Fig. 2 is a transverse sectional elevation,

of my improved device in operation,

Referring to the drawings, the frame upon which the operative parts are mounted is composed of the side pieces or planks, a a, and the 0 end pieces or crossplanks, a a, forming an open frame of such dimensions that it will rest upon each side of the pipe-trench and permit the length of pipe to be handled to pass down through the same into the trench. Upon one 3 5 of the side planks, a,and near each end thereof, are mounted in suitable bearings the axles b I), having rigidly secured thereon the drums b b.

c c are gear-wheels, also mounted upon the axles b b, and these intermesh with the worm- 0 gears d d, mounted vertically in the frames d d upon the side piece, a, the drums being gnrned in either direction by the lever-handles e e are chains or cables, one set of ends being secured-to the drums b b and the other ends being pro'vided with books ee', adapted for removable engagement with the eyes 6 e upon the side piece, c.

The operation of the device just described is as follows: The frame being placed over the v trench at the proper point and the chains 6 6 being tightened across the frame, the pipe f is rolled over upon it in a central position, as shown, and by turning the handles d d the pipe may be lowered to its position in the trench. The important feature of my invention is, however, the fact that each loweringchain is independently worked,which permits the pipe to be canted to the proper angle in order to effect a union of the pipe lowered with the length of pipe previously laid. This is necessary for the rapid and effective handling of the pipes. The pipe can be quickly and easily raised and removed from the trench by reversing the operation just described. When the pipe is lowered, the chains are to be unhooked and pulled up for the next operation.

I am aware of a device for lowering coffins in which two straps are arranged in a frame and both operated in unison by apparatus connected and worked by a single lever-handle. This construction could not be effectively used for the purpose for which my improved device is adapted.

I claim- A device for raising or lowering pipes in trenches, consisting, essentially, of a portable frame adapted to rest over the trench, provided with two separate and independent chains, one end of each being removably attached to one side of the frame and the other end of each being secured to and adapted to be Wound upon separate drums, each being adapted to be operated independently by separate gearing and lever-handles, substantially as and for the pur pose stated.

In testimony whereofI have signed my name to this specificationin the presence of two subscribing witnesses.

LEWIS BOORE.
